( 2017 ) Emended description of the family Chromatiaceae, phylogenetic analyses of the genera Alishewanella, Rheinheimera and Arsukibacterium, transfer of Rheinheimera longhuensis LH2-2T to the genus Alishewanella and description of Alishewanella alkalitolerans sp. nov. from Lonar Lake, India. PMID : 28612170 DOI : 10.1007/s10482-017-0896-5 Abstract >>
Phylogenetic analyses were performed for members of the family Chromatiaceae, signature nucleotides deduced and the genus Alishewanella transferred to Chromatiaceae. Phylogenetic analyses were executed for the genera Alishewanella, Arsukibacterium and Rheinheimera and the genus Rheinheimera is proposed to be split, with the creation of the Pararheinheimera gen. nov. Furthermore, the species Rheinheimera longhuensis, is transferred to the genus Alishewanella as Alishewanella longhuensis comb. nov. Besides, the genera Alishewanella and Rheinheimera are also emended. Strain LNK-7.1T was isolated from a water sample from the Lonar Lake, India. Cells were Gram-negative, motile rods, positive for catalase, oxidase, phosphatase, contained C16:0, C17:1�s8c, summed feature3 (C16:1�s6c and/or C16:1�s7c) and summed feature 8 (C18:1�s7c) as major fatty acids, PE and PG as the major lipids and Q-8 as the sole respiratory quinone. Phylogenetic analyses using NJ, ME, ML and Maximum parsimony, based on 16S rRNA gene sequences, identified Alishewanella tabrizica RCRI4T as the closely related species of strain LNK-7.1T with a 16S rRNA gene sequence similarity of 98.13%. The DNA-DNA similarity between LNK-7.1T and the closely related species (A. tabrizica) was only 12.0% and, therefore, strain LNK-7.1T was identified as a novel species of the genus Alishewanella with the proposed name Alishewanella alkalitolerans sp. nov. In addition phenotypic characteristics confirmed the species status to strain LNK-7.1T. The type strain of A. alkalitolerans is LNK-7.1T (LMG 29592T = KCTC 52279T), isolated from a water sample collected from the Lonar lake, India.

( 2010 ) Rheinheimera aquatica sp. nov., an antimicrobial activity producing bacterium isolated from freshwater culture pond. PMID : 21030822 Abstract >>
A bacterial strain designated GR5(T) was isolated from freshwater culture pond in Taiwan during the screening of bacteria for antimicrobial compounds and characterized using the polyphasic taxonomic approach. Strain GR5(T) was Gram-negative, aerobic, greenish-yellow colored, rod-shaped, and motile by means of a polar single flagellum. Growth occurred at 10-40 degrees C (optimum, 35 degrees C), at pH 7.0-8.0 (optimum pH 8.0) and with 0-2.0% NaCl (optimum, 0.5-1.0%). The major fatty acids were C(16:1) omega7c (36.3%), C(16:0) (16.6%), C(12:0) 3-OH (12.5%) and C(18:1) omega7c (9.1%). The major respiratory quinone was Q-8. The DNA G+C content of the genomic DNA was 51.9 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain GR5(T) belonged to the genus Rheinheimera and its most closely neighbours were Rheinheimera texasensis A62-14B(T) and Rheinheimera tangshanensis JA3-B52(T) with sequence similarities of 98.1 and 97.5%, respectively. The sequence similarities to any other recognized species within Gammaproteobacteria were less than 96.5%. The mean level of DNA-DNA relatedness between strain GR5(T) and R. texasensis A62-14B(T), the strain most closely related to the isolate, was 26.5 +/- 7.6 %. On the basis of the phylogenetic and phenotypic data, strain GR5(T) should be classified as representing a novel species, for which the name Rheinheimera aquatica sp. nov. is proposed. The type strain is GR5(T) (= BCRC 80081(T) = LMG 25379(T)).
